IPC: G11C11/22
Filed: 1996-09-13
Abstract: PROBLEM TO BE SOLVED: To prevent breakdown of a memory data by introducing a structure to control at least one electrode among both electrodes of a memory cell to a high impedance during the period until the power supply is stabilized when the power is turned ON. SOLUTION: Capacitance of a capacitor 35 is set larger than a gate parasitic capacitance of an N type MOS transistor(Tr) 34 and is determined by a product (time constant) with a resistance value of a resistor 36. This time constant is the time required for fixing the word line 7 to L level after the Tr 34 is turned ON due to the turning ON of the power supply and is obtained by using each element having the delay times of D to D4. Therefore, while the period until the power supply is stabilized, the line 7 is fixed to the L level by a potential stabilizing circuit 30. Next, when the chip enable line 20 is fixed to the L level, the line 7 is fixed to the H level by an OR circuit 22 after the time D1 and a cell plate electrode 8 is fixed to the H level by an AND circuit 22 after the time D3.  Next, when the line 8 is fixed to the H level, the electrode 8 is fixed to the L level after the time D4 and the line 7 is fixed to the L level after the time D1+D2. Thereby, data breakdown of the memory cell can be prevented.

Title: Roll gap regulator
Inventor: OOSUGI YASUO
IPC: B29C48/90
Filed: 1994-10-07
Abstract: PURPOSE: To provide a roll gap regulator which has sufficient durable force even if a strong pressing force is received and can finely regulate the gaps of the rolls. CONSTITUTION: When an initial sheet 3 is passed, a touch roll 7 is waited at the position sufficiently separated from a casting roll 4 by the operation of a hydraulic cylinder 28. When the sheet is passed and a molten resin sheet 3 is fed while being rolled on the roll 4 from the die 2 of an extruder, the roll 7 is pressed by the cylinder 28 to be brought into contact with the sheet 3, and sandwiched under pressure to the roll 4. Since the roll 7 is driven at the same speed as the peripheral speed of the roll 4 at the peripheral speed of the roll surface, the sheet 3 is not caused by a shearing strain in the flowing direction. Then, when the roll interval is regulated, the display value of a distance measuring sensor 45 is observed to confirm the size of the gap, and then an eccentric shaft is rotated to regulate the gap interval between the rolls 4 and 7.

Abstract: PURPOSE:To prevent an optical output from being changed by temperature with simple constitution by comparing the optical output of a semiconductor laser driven by a prescribed waveform with a set point to control the drive of the laser. CONSTITUTION:The voltage of a waveform boosted in accordance with the lapse of time is supplied from a saw tooth wave generating means 20 to the semiconductor laser 22 through a voltage/current converter 21, the optical output of the laser 22 is monitored by a photodiode 23 and voltage Vm corresponding to light reception is outputted from a current/voltage converter 24. On the other hand, a look-up table 27 is referred in accordance with pixel data and a set voltage (e) corresponding to the pixel data is outputted from a D/A converter 28. When the voltage Vm reaches the voltage (e), an FF 25 is reset by the comparing output of a comparator 26, a switch 31 is turned off and the current of a waveform to be increased in accordance with the supplying time to the diode 22 is interrupted. Since the device adops the simple constitution using saw-tooth waves without using rectangular waveforms complexing the structure, the optical output of the laser diode 22 can be prevented from being varied even when the characteristics of the diode 22 are changed in accordance with temperature.
